IMO Ans is B
Stmt 1
X^2/(XY+X) < 1 this can be written as
(XY+X)/X^2 > 1 => (Y+1)/X > 1 => Y+1 > X
means X=Y or Y>X
Stmt2
XY/(Y^2-Y) < 1 I assumed this is what you mean
(Y^2-Y)/XY > 1 => Y-1/X > 1 => Y-1 > X means Y>X
Stmt 1
X^2/(XY+X) < 1 this can be written as
(XY+X)/X^2 > 1 => (Y+1)/X > 1 => Y+1 > X
means X=Y or Y>X
Stmt2
XY/(Y^2-Y) < 1 I assumed this is what you mean
(Y^2-Y)/XY > 1 => Y-1/X > 1 => Y-1 > X means Y>X
